The reasing I "haha" XD is because I read a book called "Daughter of Smoke and Bone" and there's this human girl with blue hair who meets this SUPER HOT ANGEL with beautiful "tiger eyes" and after they start to talk the angel meets the girl's best friend and she is almost less than 5 feet but feels big at heart and when she was about to interrogate him and insult him she just stood there with her mouth open and looked at her best friends saying "OMG-SEXY-MATE-NOOOWW!" and the funny thing is that the angel doesn't understand the human language and she is saying to him out loud "SEXY!! MATE!!" and the blue haired girl so embarrassed but greatful that he doesn't understand their human language, (but the blue haired girl knows the angel's language and that's why they can communicate with each other)
